With the exception of the poet, who is quite conservative and traditional, they universally participate in the leftist hivemind. All of them (including the conservative) are quite eccentric sexually, and in different ways, based on what they have said and I have seen. Beyond that, they are only eccentric in the particular calculus of their flaws, as is each individual when closely observed.
One had the loveliest wife you'd ever want to meet, a great match for each other, yet he couldn't stop himself from having serial affairs. He even asked me and others for help 15 years ago, but couldn't stop. He is now a lonely middle-aged guy striving to paper over the self-inflicted pain. (I know this, despite his denials, because I've known him for over 30 years.)
One has been completely inactive as far as I can tell, but the sense of "repression" has always been strong. I have no idea what the root of this is, but mutual friends have all commented on it at some point.
As for the remainder, it is best to draw the curtain of modesty over the scene.
